摘要:
A camera lens control system that has improved flexibility and lens control precision in various configurations. The camera lens control system has a handle that is wirelessly connected to a control motor for controlling focus, zoom, or aperture of a lens. In addition, the handle is used to maneuver the camera during shooting. The camera lens control system includes one or more control motors that can be connected in series to share power and control signals.

An actuator is provided for driving a camera module to perform a focusing operation. The actuator includes a carrier part, a base, a driving module, and plural balls. The carrier part is used for supporting the camera module and the plural balls. The base is used for accommodating the carrier part. The driving module is used for driving movement of the carrier part. The driving module is located at a corner of the carrier part. The plural balls are located at other corners of the carrier part. The carrier part is guided by the plural balls to be moved in a direction parallel with an optical axis of the camera module.

Surveillance networks are used to observe large areas, like public places, streets, public buildings or private houses, privates premises etc. The surveillance networks often comprise a plurality of surveillance cameras. Such surveillance cameras should be small, robust, trouble-free and have low-maintenance requirements. Subject-matter of the invention is a linear actuator (8) for a linear motion of a component of a camera (1), the linear actuator comprising a supporting structure (6), a motor (10) arranged on the supporting structure for generating a rotational movement, a component carrier (7) for carrying the component and for performing the linear motion relative to the supporting structure, a gear mechanism (11) for transmitting the rotational movement, whereby the last gear of the gear mechanism before the component carrier is a transfer gear (20), whereby the transfer gear comprises a guide way (23a, b, c) extending in rotational direction of the transfer gear with a slope along the guide way whereby the component carrier is coupled with the guide way by resting means (24a, b, c), so that the component carrier is displaced in the linear direction (9) by a rotational movement of the transfer gear due to the slope of the guide way.

An image sensing apparatus including: an image sensor (107) including a plurality of focus detection pixel pairs (S HA , S HB , S VC and S VD ) that perform photoelectric conversion on each pair of light beams that have passed through different regions of a photographing lens (100) and output an image signal pair; a flash memory (133) that stores shift information (177) on relative shift between an optical axis of the photographing lens (100) and a central axis of the focus detection pixel pairs (S HA , S HB , S VC and S VD ); a correction unit (170) that corrects a signal level of the image signal pair based on the shift information and (177) exit pupil information (176) of the photographing lens (100) so as to compensate for an unbalanced amount of light that enters each of the focus detection pixel pairs (S HA ,S HB , S VC and S VD ); and a focus detection unit (901) that detects a focus of the photographing lens (100) using the image signal pair corrected by the correction unit (170).

There is provided a domed monitoring camera apparatus allowing reduction of a shift in focus dependent on a variation in optical path length caused by a dome cover. The domed monitoring camera apparatus (1) includes a monitoring camera (3), a dome cover (5) which covers the monitoring camera (3), and a camera controller (25). The camera controller (25) functions as an adjustment unit which, when the dome cover (5) is attached, adjusts the focus of the monitoring camera (3) with the cover attached to correct a variation in optical path length caused by the dome cover (5). The camera controller (25) adjusts the focus of the monitoring camera (3) with the cover attached according to an optical path length affecting cover parameter which represents a dome cover character relative to increase or decrease of the optical path length of the monitoring camera (3).
摘要:
A device, method and a computer program product are shown for correcting the focus error in an optical device, wherein in a first position of the optical device at least one focus detector is focused onto a given image plane of the target subject and the distance (d1) between the optical device and the given image plane is locked and wherein in a second position of the optical device following a reorientation of the optical device for achieving the desired framing of the image the shutter is released, the method comprising sensing a distance vector parallel to the focus plane after reorientation between the first position and the second position after reorientation, calculating a focus correction value (de) from the sensed distance vector and adding the focus correction value (de) as a corrective to the locked focus distance (d1).
